Heating and Cooling on at same time
The heating and cooling units are activated at the same time. Is this a problem with thermostat?
I have a Honeywell Chronotherm III thermostat that was replaced with a Chronotherm IV. They were models 8602.

Did it start right after the thermostat was replaced? Maybe a couple bare wires are touching at the terminals?? Or maybe a couple wires are in the wrong place? The thermostat has a built in deadband between heating and cooling. That could out of whack but we need to check the wiring first.
